Carboxylated polysaccharides 6-substituted |
摘要 |
A new class of polysaccharides containing carboxylic groups selectively substituted with halogens on the carbon atom on position 6 of the glicopyranosidic residue and the procedure to obtain these derivatives is therein described. The procedure entails the halogenation of carboxylated polysaccharides with alkyl aryl sulfonyl-halides in organic solvent. The products of this invention can be used as substrates in synthesis where the reactive site is the carbon that binds the halogen. Moreover, they can be used in the medical-diagnostic field. |
